How to convert any Time zone date to GMT time zone

[SivaKumar123]

I need to convert any time zone to the GMT time zone.

Variable names: Escalation date and Probably date'

Type: Date /Time

Need to update the time zone on the variable name: Start date, End date, and type : single text.

Please help me with the code.

function onChange(control, oldValue, newValue, isLoading) {
if (isLoading || newValue == '') {

return;
}

var start = g_form.getValue('escalation_date');
var end = g_form.getValue('probably_date');

g_form.setValue('MST_start_date', toMST(start));

g_form.setValue('MST_end_date', toMST(end));
}

function toMST(start){
var time = new GlideDateTime(start);
var tz = Packages.java.util.TimeZone.getTimeZone("GMT");
time.setTZ(tz);
var timeZoneOffSet = time.getTZOffset();
time.setNumericValue(time.getNumericValue() + timeZoneOffSet);
return time;
}

GlideDateTime is not working in client side script, please try the Date object

function onChange(control, oldValue, newValue, isLoading) {
if (isLoading || newValue == '') {
     return;
}

var start = g_form.getValue('escalation_date');
var end = g_form.getValue('probably_date');

g_form.setValue('MST_start_date', new Date(start).toUTCString());
g_form.setValue('MST_end_date', new Date(end).toUTCString());
}

Just to add for anyone else. I used the solution in an onSubmit client script and it worked for me too.
